MEASURlNG-VESSEL.

SPECIFICATION forming part of Letters Patent No. 377,369, dated February 7, 1888.

Application filed May 7, 1887.

To all whom it may concern.-

Be it known that I, J OsEPH O. Bocas, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in llieasuring-Vessels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which--A Figure l represents a front elevation of a measuring-vessel embodying my invention.

Fig. 2 is a sectional view of the same on the line X X of Fig. l.

My invention relates to vessels for `measuring liquids; and it consists, essentially, in a vessel or chamber containing air and connected with theliquid-containing barrel or vessel, so that when the contents ofthe latter are being drawn off in predetermined quantities a like amount or quantity of air is drawn from the air-chamberinto the liquid-containing barrel or vessel to take the place of the displaced liquid. Y

My invention alsoconsists in connecting with the movable dome of an air vessel or chamber an indicating device for determining the amount of air displaced in said vessel andthe consequent amount of liquid drawn from the'4 barrel.

My invention further consists in the peculiar construction and combination of devices, which I shall hereinafter fully describe and claim.

rIo enable others skilled in the art to make and use my invention, I will describe its construction and indicate the manner in which the same is carried out.

In the said drawings, A represents an exterior vessel having a coupling, a., by means of which saidvessel and its connections may be attached to a liquid-containing barrel or cask, the said coupling being adapted to be screwed into the bung-hole or any part of the top of the barrel or Cask A. The said coupling is provided with a suitable valve, B, by means of which communication between the air and liquid-containing vessels may be opened and closed. A pipe or tube, C, extends upwardly from the center of the vessel A, and is in direct communication with the usual opening through Serial No. 237,414. (No model.)

the coupling, as shown in Fig. 2, and a dome or inverted vessel, D, is suitably suspended over and guided by the tube, the .said vessel having at its lower open end a sleeve through which said tube passes. In the lower portion of the exterior' is placed oil, Water, or other y liquid, into which the lower end ofthe inverted vessel dips, whereby a tight joint or seal is formed to prevent the admission or escape of air between said tube or vessel.

To the top of thevesselD one end ofa cable or cord is attached, said cable passing over guide-pulleys E on top of the exterior vessel,

A, and being connected at its other end to a rod, F, on which is mounted a Weight, G, the said Weight and rod being guided lin their movements by a plate, H, the other face of which is provided with graduations or marks indicating the capacity of the measure. A pointer or index, I, on the Weight extends through a slot, e, in the plate H, and in conjunction with the graduations before mentioned indicates the amount of air drawn from the measure and the Aconsequent quantity of liquid drawn from the barrel or cask to which said measure is attached.

The operation of my measure is substantially as follows: Itis wellknown that a given amount of liquid drawn from a barrel or vessel requires a like amount of air to replace it or to iill the vacuum created by drawing off theliquid. To accomplish this feature I till the exterior vessel up to a point three-fourths of an inch from the top of the tube or pipe C with oil, water, or other liquid, and permit the inverted vessel to rest upon said body of liquid with its lower edge dipping into the same. The pointer or index is now adjusted, by loosening the screw which holds it in place on the movable weight, to the Zero-point on the contiguous scale. The measure having been properly secured to the barrel or cask and communication between said measure and barrel being established, it

is evident that if a given amount of liquid be drawn 'from said barrel a like amount of air must be drawn from the air chamber or dome D to ll the vacuum thus created. rIherefore as the liquid is being drawn from the barrel the inverted vessel or dome begins to sink, drawing upon the pointer upon the outside of the vessel A and indicating the exact amount IOO of liquid drawn from the barrel. By moving the valve-operating lever J into avertical position Icommunication is cut off between the measure and barrel, and the pointer may be drawn back to the Zero-point Without difficulty, and as the dome D rises Voutside air rushes in through a small port, g, andchargcs said dome, so that it may again operate to in'- dicate the amount of liquid taken from the barrel, it being understood that the port g is closed by the valve B when direct communication is established between the measure and barrel. y The device herein described is capable of varied changes and modifications. I therefore do not wish to bc understood as confining-:myselfto any particular form or capacity of meas,- ure or to the manner of connecting the same to the liquid-containing vessel, as these may be changed to meet existing circumstances.

Having thus described my invention, what I Y claim as new, and desire tosecure by Letters Patent, isl. A vessel or measure containing` air under pressure and an indicating device connected therewith, in combination with a liquid-con` taining vessel communicating with the interior of said measure, substantially as described.

2. The combination, with a liquid-containing vessel, ol" an air-vessel communicating therewith and an indicating apparatus on said air-vessel, whereby a given amount of liquidthe liquid removed, and inattaching to said 3 The method of indicating the amount of 35 liquid drawn from a Vessel, consisting in connecting said vessel with an air chamber or ves sel, which supplies the liquid-containing vessel with air in quantities corresponding with air-vessel a device for indicating theamount of displaced air, substantially as herein described.

4. The combination, with a liquid-containing vessel, of an airmeasure comprising an eX- teriorvessel having an air tube or pipe, an internal vertically-moving dome or chamber containingair and communicating with said tube or pipe, and an exteriorindicating device operated by the dome or chamber to Aregister 5 both the amount of air removed from said dome or chamber and the amount of liquid drawn from the vessel, substantially as `dc scribed.

5. An air-measure having an indicating ap 5 paratus, in combination with a liquidvcontain` ing barrel or Vessel vcommunicating with and drawing` air therefrom iu amounts correspond ing to the amounts of liquid withdrawn, substanti-all y as herein described.
